I am still having trouble with this machine, specifically the GPUs. I set up some 120mm fans to blow cool air from the side. This lowered the GPU temps by a few degrees Celsius but they were not getting too hot anyway. So, I think I have ruled out problems with RAM, hard drives...

No, I only tried two PSUs (the Cooler Master 1200W, now replaced with a Rosewill Hercules 1600W). When I first had this problem with the machine hanging, I upgraded the PSU. This was because the other very similar machine had the 1500W ThermalTake, and I still have had no problems running that...

I tried stressing the machine with all combinations of components, starting with the RAM and moving on to individual GPUs, then combinations of the GPUs. So far the only condition under which the machine fails is when 3 or 4 GPUs are running at the same time - with 1 or 2 GPUs, the stress test...

About 1.5 years ago I built two machines to do some image processing with GPUs. Both machines are identical except for PSU: Mobo: ASUS P6T7 CPU: Intel i7-960 case: Lian Li Lancool PC-K58 PSU: Machine 1 had a Cooler Master 1200W, now replaced with a Rosewill Hercules 1600W, machine 2 has...

I'm looking to build one or more PCs for calculations in a physics lab (mostly large fast Fourier transforms). The task is very computationally demanding, but does not require much RAM (~1GB) or storage (2TB). I have benchmarked GPUs previously and found them to be by far the most cost...
